webpack TS2304 Cannot find name 'Map', 'Set', 'Promise'

Question

I have the following webpack.config.js

var path = require(\"path\");
var webpack = require(\'webpack\');

module.exports = {
  entry: {
    \'ng2-auto-comple         


        

Answer 1

To solve this you only need to import map method in your ts file like this:

import { map } from 'rxjs/operators';

Answer 2

Map, Set and Promise are ES6 features.
In your tsconfig.json you are using:

"target": "es5" 

This causes the compiler to use the normal es5 lib.d.ts, which lacks the definitions for the above types.

You want to use the lib.es6.d.ts:

"target": "es6" 

Answer 3

In your tsconfig.json just change "target": "es5" to "target": "es6"
